[ 1 ] - Study structural and up-conversion luminescence properties of polyvinyl alcohol/CaF2:erbium nanofibers for potential medical applications
Objective(s): This paper describes synthesisPolyvinyl Alcohol/CaF2:Er nanofibers because of its photoluminescence properties.Materials and Methods: First, CaF2:Er nanocomposite synthesized with co-precipitation method. In order to prepare polyvinyl alcohol (PVA)/CaF2:Er nanofibers, CaF2:Er nanocomposites were added to the polyvinyl alcohol (PVA) polymer. PVA/CaF2:Er composite nanofibers were...
[ 2 ] - Synthesis and study of structural and magnetic properties of superparamagnetic Fe3O4@SiO2 core/shell nanocomposite for biomedical applications
Objective(s): This paper describes coating of magnetite nanoparticles (MNPs) with amorphous silica shells. Materials and Methods: First, magnetite (Fe3O4) NPs were synthesized by co-precipitation method and then treated with stabilizer molecule of trisodium citrate to enhance their dispersibility. Afterwards, coating with silica was carried out via a sol-gel approach in which the electrostati...
